Gender Communication Differences on a Pediatric Provider Listserv.

BACKGROUND AND OBJECTIVES: Gender-based communication differences are described in educational online communities, but have not been rigorously evaluated in medical online communities. Understanding gender differences in communication may provide insight into gender disparities in the medical profession. Our objective was to describe gender differences in post frequency, content, and language styles on the American Academy of Pediatrics Section on Hospital Medicine (SOHM) listserv. METHODS: Posts were obtained from publicly available SOHM listserv archives. The first month of every quarter of 2019 and 2020 were reviewed. Two reviewers assigned a post topic (clinical, research, etc) and format (question vs statement) to all deidentified original posts (K = 1.0 topic, 0.89 format). Six trained reviewers assigned language styles (intraclass coefficient = 0.73, indicating good agreement). RESULTS: We analyzed 1592 posts: 287 original posts and 1305 responses. Frequency: Women authored 50% of posts. The 9 most frequent posters (7 men, 2 women) accounted for 19.5% of posts. Content: Men's posts had more words than women's (132.51 vs 112.3, P ≤ .01). Men were more likely to post about health policy and research (P < .001). Men were more likely to post statements compared with women (39% vs 21%, P < .001). Style: Men's posts were more likely to be coded adversarial (12.3% vs 5.5%, P < .001) authoritative (12.2% vs 6.5%, P < .001) or self-amplifying (6.5% vs 3.6%, P < .001). CONCLUSIONS: Women contribute disproportionately fewer posts to the American Academy of Pediatrics SOHM listserv compared with their percentage in the subspecialty. We noted significant gender differences in language style and content, which may impact career development and online community inclusion.

A multicenter randomized trial to compare automatic versus as-needed follow-up for children hospitalized with common infections: The FAAN-C trial protocol.

INTRODUCTION: Physicians commonly recommend automatic primary care follow-up visits to children being discharged from the hospital. While automatic follow-up provides an opportunity to address postdischarge needs, the alternative is as-needed follow-up. With this strategy, families monitor their child's symptoms and decide if they need a follow-up visit in the days after discharge. In addition to being family centered, as-needed follow-up has the potential to reduce time and financial burdens on both families and the healthcare system. As-needed follow-up has been shown to be safe and effective for children hospitalized with bronchiolitis, but the extent to which hospitalized children with other common conditions might benefit from as-needed follow-up is unclear. METHODS: The Follow-up Automatically versus As-Needed Comparison (FAAN-C, or "fancy") trial is a multicenter randomized controlled trial. Children who are hospitalized for pneumonia, urinary tract infection, skin and soft tissue infection, or acute gastroenteritis are eligible to participate. Participants are randomized to an as-needed versus automatic posthospitalization follow-up recommendation. The sample size estimate is 2674 participants and the primary outcome is all-cause hospital readmission within 14 days of discharge. Secondary outcomes are medical interventions and child health-related quality of life. Analyses will be conducted in an intention-to-treat manner, testing noninferiority of as-needed follow-up compared with automatic follow-up. DISCUSSION: FAAN-C will elucidate the relative benefits of an as-needed versus automatic follow-up recommendation, informing one of the most common decisions faced by families of hospitalized children and their medical providers. Findings from FAAN-C will also have implications for national quality metrics and guidelines.

Prescribing Patterns of Nonrecommended Medications for Children With Acute COVID-19.

OBJECTIVE: Repurposed medications for acute coronavirus disease 2019 (COVID-19) continued to be prescribed after results from rigorous studies and national guidelines discouraged use. We aimed to describe prescribing rates of nonrecommended medications for acute COVID-19 in children, associations with demographic factors, and provider type and specialty. METHODS: In this retrospective cohort of children <18 years in a large United States all-payer claims database, we identified prescriptions within 2 weeks of an acute COVID-19 diagnosis. We calculated prescription rate, performed multivariable logistic regression to identify risk factors, and described prescriber type and specialty during nonrecommended periods defined by national guidelines. RESULTS: We identified 3 082 626 COVID-19 diagnoses in 2 949 118 children between March 7, 2020 and December 31, 2022. Hydroxychloroquine (HCQ) and ivermectin were prescribed in 0.03% and 0.14% of COVID-19 cases, respectively, during nonrecommended periods (after September 12, 2020 for HCQ and February 5, 2021 for ivermectin) with considerable variation by state. Prescription rates were 4 times the national average in Arkansas (HCQ) and Oklahoma (ivermectin). Older age, nonpublic insurance, and emergency department or urgent care visit were associated with increased risk of either prescription. Additionally, residence in nonurban and low-income areas was associated with ivermectin prescription. General practitioners had the highest rates of prescribing. CONCLUSIONS: Although nonrecommended medication prescription rates were low, the overall COVID-19 burden translated into high numbers of ineffective and potentially harmful prescriptions. Understanding overuse patterns can help mitigate downstream consequences of misinformation. Reaching providers and parents with clear evidence-based recommendations is crucial to children's health.

Prioritization of Randomized Clinical Trial Questions for Children Hospitalized With Common Conditions: A Consensus Statement.

Importance: There is a lack of randomized clinical trial (RCT) data to guide many routine decisions in the care of children hospitalized for common conditions. A first step in addressing the shortage of RCTs for this population is to identify the most pressing RCT questions for children hospitalized with common conditions. Objective: To identify the most important and feasible RCT questions for children hospitalized with common conditions. Design, Setting, and Participants: For this consensus statement, a 3-stage modified Delphi process was used in a virtual conference series spanning January 1 to September 29, 2022. Forty-six individuals from 30 different institutions participated in the process. Stage 1 involved construction of RCT questions for the 10 most common pediatric conditions leading to hospitalization. Participants used condition-specific guidelines and reviews from a structured literature search to inform their development of RCT questions. During stage 2, RCT questions were refined and scored according to importance. Stage 3 incorporated public comment and feasibility with the prioritization of RCT questions. Main Outcomes and Measures: The main outcome was RCT questions framed in a PICO (population, intervention, control, and outcome) format and ranked according to importance and feasibility; score choices ranged from 1 to 9, with higher scores indicating greater importance and feasibility. Results: Forty-six individuals (38 who shared demographic data; 24 women [63%]) from 30 different institutions participated in our modified Delphi process. Participants included children's hospital (n = 14) and community hospital (n = 13) pediatricians, parents of hospitalized children (n = 4), other clinicians (n = 2), biostatisticians (n = 2), and other researchers (n = 11). The process yielded 62 unique RCT questions, most of which are pragmatic, comparing interventions in widespread use for which definitive effectiveness data are lacking. Overall scores for importance and feasibility of the RCT questions ranged from 1 to 9, with a median of 5 (IQR, 4-7). Six of the top 10 selected questions focused on determining optimal antibiotic regimens for 3 common infections (pneumonia, urinary tract infection, and cellulitis). Conclusions and Relevance: This consensus statementhas identified the most important and feasible RCT questions for children hospitalized with common conditions. This list of RCT questions can guide investigators and funders in conducting impactful trials to improve care and outcomes for hospitalized children.

Incidence of Pediatric Urinary Tract Infections Before and During the COVID-19 Pandemic.

IMPORTANCE: Urinary tract infection (UTI) is common in children, but the population incidence is largely unknown. Controversy surrounds the optimal diagnostic criteria and how to balance the risks of undertreatment and overtreatment. Changes in health care use during the COVID-19 pandemic created a natural experiment to examine health care use and UTI diagnosis and outcomes. OBJECTIVES: To examine the population incidence of UTI in children and assess the changes of the COVID-19 pandemic regarding UTI diagnoses and measures of UTI severity. DESIGN, SETTING, AND PARTICIPANTS: This retrospective observational cohort study used US commercial claims data from privately insured patients aged 0 to 17 years from January 1, 2016, to December 31, 2021. EXPOSURE: Time periods included prepandemic (January 1, 2016, to February 29, 2020), early pandemic (April 1 to June 30, 2020), and midpandemic (July 1, 2020, to December 31, 2021). MAIN OUTCOMES AND MEASURES: The primary outcome was the incidence of UTI, defined as having a UTI diagnosis code with an accompanying antibiotic prescription. Balancing measures included measures of UTI severity, including hospitalizations and intensive care unit admissions. Trends were evaluated using an interrupted time-series analysis. RESULTS: The cohort included 13 221 117 enrollees aged 0 to 17 years, with males representing 6 744 250 (51.0%) of the population. The mean incidence of UTI diagnoses was 1.300 (95% CI, 1.296-1.304) UTIs per 100 patient-years. The UTI incidence was 0.86 per 100 patient-years at age 0 to 1 year, 1.58 per 100 patient-years at 2 to 5 years, 1.24 per 100 patient-years at 6 to 11 years, and 1.37 per 100 patient-years at 12 to 17 years, and was higher in females vs males (2.48 [95% CI, 2.46-2.50] vs 0.180 [95% CI, 0.178-0.182] per 100 patient-years). Compared with prepandemic trends, UTIs decreased in the early pandemic: -33.1% (95% CI, -39.4% to -26.1%) for all children and -52.1% (95% CI, -62.1% to -39.5%) in a subgroup of infants aged 60 days or younger. However, all measures of UTI severity decreased or were not significantly different. The UTI incidence returned to near prepandemic rates (-4.3%; 95% CI, -32.0% to 34.6% for all children) after the first 3 months of the pandemic. CONCLUSIONS AND RELEVANCE: In this cohort study, UTI diagnosis decreased during the early pandemic period without an increase in measures of disease severity, suggesting that reduced overdiagnosis and/or reduced misdiagnosis may be an explanatory factor.

Clinical Course of Children 1 to 24 Months Old With Positive Urine Cultures Without Pyuria.

OBJECTIVE: To describe the clinical course of children with positive urine cultures without pyuria who were not given antibiotics initially, identify predictors of subsequent antibiotic treatment, and evaluate the association between subsequent treatment and urinary tract infection (UTI) within 30 days. METHODS: We conducted a multicenter retrospective cohort study of children 1 to 24 months old who had positive urine cultures without pyuria and who were not started on antibiotics upon presentation to 3 health care systems from 2010 to 2021. Outcomes included clinical status at the time urine cultures resulted, escalation of care (emergency department visit or hospitalization) and subsequent antibiotic treatment within 7 days, and subsequent UTI within 30 days of presentation. RESULTS: Of 202 included children, 61% were female and median age was 9 months. Of 151 patients with clinical status information when cultures resulted, 107 (70.8%, 95% confidence interval [CI] 62.9-77.9%) were improved. Two of 202 children (1.0%, 95% CI 0.2-4.0%) experienced care escalation. Antibiotics were started in 142 (82.2%) children, and treatment was associated with prior UTI (risk ratio [RR] 1.20, 95% CI 1.15-1.26) and lack of improvement (RR 1.22, 95% CI 1.13-1.33). Subsequent UTI was diagnosed in 2 of 164 (1.2%, 95% CI 0.1-4.3%) treated and 0 of 36 (0%, 95% CI 0-9.7%) untreated children. CONCLUSIONS: Seventy percent of children with positive urine cultures without pyuria improved before starting antibiotics; however, >80% were ultimately treated. Future research should study the impact of diagnostic stewardship interventions and various urine testing strategies to optimize the management of children evaluated for UTI.retain-->.

Trends in Low-Value Care Among Children's Hospitals.

BACKGROUND AND OBJECTIVES: Longitudinal pediatric low-value care (LVC) trends are not well established. We used the Pediatric Health Information System LVC Calculator, which measures utilization of 30 nonevidenced-based services, to report 7-year LVC trends. METHODS: This retrospective cohort study applied the LVC Calculator to emergency department (ED) and hospital encounters from January 1, 2016, to December 31, 2022. We used generalized estimating equation models accounting for hospital clustering to assess temporal changes in LVC. RESULTS: There were 5 265 153 eligible ED encounters and 1 301 613 eligible hospitalizations. In 2022, of 21 LVC measures applicable to the ED cohort, the percentage of encounters with LVC had increased for 11 measures, decreased for 1, and remained unchanged for 9 as compared with 2016. Computed tomography for minor head injury had the largest increase (17%-23%; P < .001); bronchodilators for bronchiolitis decreased (22%-17%; P = .001). Of 26 hospitalization measures, LVC increased for 6 measures, decreased for 9, and was unchanged for 11. Inflammatory marker testing for pneumonia had the largest increase (23%-38%; P = .003); broad-spectrum antibiotic use for pneumonia had the largest decrease (60%-48%; P < .001). LVC remained unchanged or decreased for most medication and procedure measures, but remained unchanged or increased for most laboratory and imaging measures. CONCLUSIONS: LVC improved for a minority of services between 2016 and 2022. Trends were more favorable for therapeutic (medications and procedures) than diagnostic measures (imaging and laboratory studies). These data may inform prioritization of deimplementation efforts.

Misclassification of Both Influenza Infection and Oseltamivir Exposure Status in Administrative Data.

This cross-sectional study examines documented hospitalization for influenza and administration of neuraminidase inhibitors in US children.

Incidence of Neonatal Hypothermia in the Newborn Nursery and Associated Factors.

Importance: Thermoregulation is a key component of well-newborn care. There is limited epidemiologic data on hypothermia in late preterm and term infants admitted to the nursery. Expanding on these data is essential for advancing evidence-based care in a population that represents more than 3.5 million births per year in the US. Objective: To examine the incidence and factors associated with hypothermia in otherwise healthy infants admitted to the newborn nursery following delivery. Design, Setting, and Participants: A retrospective cohort study using electronic health record data from May 1, 2015, to August 31, 2021, was conducted at a newborn nursery at a university-affiliated children's hospital. Participants included 23 549 infants admitted to the newborn nursery, from which 321 060 axillary and rectal temperature values were analyzed. Exposures: Infant and maternal clinical and demographic factors. Main Outcomes and Measures: Neonatal hypothermia was defined according to the World Health Organization threshold of temperature less than 36.5 °C. Hypothermia was further classified by severity (mild: single episode, temperature 36.0-36.4 °C; moderate/severe: persistent or recurrent hypothermia and/or temperature <36.0 °C) and timing (early: all hypothermic episodes occurred within the first 24 hours after birth; late: any episode extended beyond the first 24 hours). Results: Of 23 549 included infants (male, 12 220 [51.9%]), 5.6% were late preterm (35-36 weeks' gestation) and 4.3% were low birth weight (≤2500 g). The incidence of mild hypothermia was 17.1% and the incidence of moderate/severe hypothermia was 4.6%. Late hypothermia occurred in 1.8% of infants. Lower birth weight and gestational age and Black and Asian maternal race and ethnicity had the highest adjusted odds across all classifications of hypothermia. The adjusted odds ratios of moderate/severe hypothermia were 5.97 (95% CI 4.45-8.00) in infants with a birth weight less than or equal to 2500 vs 3001 to 3500 g, 3.17 (95% CI 2.24-4.49) in 35 week' vs 39 weeks' gestation, and 2.65 (95% CI 1.78-3.96) in infants born to Black mothers and 1.94 (95% CI 1.61-2.34) in infants born to Asian mothers vs non-Hispanic White mothers. Conclusions and Relevance: In this cohort study of infants in the inpatient nursery, hypothermia was common, and the incidence varied by hypothermia definition applied. Infants of lower gestational age and birth weight and those born to Black and Asian mothers carried the highest odds of hypothermia. These findings suggest that identifying biological, structural, and social determinants of hypothermia is essential for advancing evidence-based equitable thermoregulatory care.

Perspectives of Health Care Personnel on the Benefits of Bronchiolitis Interventions.

OBJECTIVES: Many interventions in bronchiolitis are low-value or poorly studied. Inpatient bronchiolitis management is multidisciplinary, with varying degrees of registered nurse (RN) and respiratory therapist (RT) autonomy. Understanding the perceived benefit of interventions for frontline health care personnel may facilitate deimplementation efforts. Our objective was to examine perceptions surrounding the benefit of common inpatient bronchiolitis interventions. METHODS: We conducted a cross-sectional survey of inpatient pediatric RNs, RTs, and physicians/licensed practitioners (P/LPs) (eg, advanced-practice practitioners) from May to December of 2021 at 9 university-affiliated and 2 community hospitals. A clinical vignette preceded a series of inpatient bronchiolitis management questions. RESULTS: A total of 331 surveys were analyzed with a completion rate of 71.9%: 76.5% for RNs, 57.4% for RTs, and 71.2% for P/LPs. Approximately 54% of RNs and 45% of RTs compared with 2% of P/LPs believe albuterol would be "extremely or somewhat likely" to improve work of breathing (P < .001). Similarly, 52% of RNs, 32% of RTs, and 23% of P/LPs thought initiating or escalating oxygen in the absence of hypoxemia was likely to improve work of breathing (P < .001). Similar differences in perceived benefit were observed for steroids, nebulized hypertonic saline, and deep suctioning, but not superficial nasal suctioning. Hospital type (community versus university-affiliated) did not impact the magnitude of these differences. CONCLUSIONS: Variation exists in the perceived benefit of several low-value or poorly studied bronchiolitis interventions among health care personnel, with RNs/RTs generally perceiving higher benefit. Deimplementation, educational, and quality improvement efforts should be designed with an interprofessional framework.

Concordance between electronic health record-recorded race/ethnicity and parental report in hospitalized children.

BACKGROUND: Electronic health records (EHRs) have become an important repository for patient race and ethnicity. Misclassification could negatively affect efforts to monitor and reduce health disparities and structural discrimination. OBJECTIVE: We assessed the concordance of parental reports of race/ethnicity for their hospitalized children with EHR-documented demographics. We also aimed to describe parents' preferences on how race/ethnicity should be captured in the hospital's EHR. DESIGNS, SETTINGS, AND PARTICIPANTS: From December 2021 to May 2022, we conducted a single-center cross-sectional survey of parents of hospitalized children asking to describe their child's race/ethnicity and compared these responses to the race/ethnicity documented in the EHR. MAIN OUTCOME AND MEASURES: Concordance was analyzed with a kappa statistic (κ). Additionally, we queried respondents about their awareness of and preferences for race/ethnicity documentation. RESULTS: Of the 275 participants surveyed (79% response rate), there was 69% agreement (κ = 0.56) for race and 80% agreement (κ = 0.63) for ethnicity between parent report and EHR documentation. Sixty-eight parents (21%) felt that the designated categories poorly represent their child's race/ethnicity. Twenty-two (8%) were uncomfortable with their child's race/ethnicity being displayed on the hospital's EHR. Eighty-nine (32%) preferred a more comprehensive list of race/ethnicity categories. CONCLUSIONS: Nonconcordance between EHR-recorded race/ethnicity and parental report exists in the EHR for our hospitalized patients, which has implications for describing patient populations and for understanding racial and ethnic disparities. Current EHR categories may be limited in their ability to capture the complexity of these constructs. Future efforts should focus on ensuring that demographic information in the EHR is accurately collected and appropriately reflects families' preferences.

Performance of a Provider-Assigned Functional Outcome Score in Critically Ill Children.

OBJECTIVES: Determine agreement between Pediatric Cerebral Performance Category (PCPC) scores integrated into clinical workflow and traditional investigator-assigned scores. DESIGN: Longitudinal study. SETTING: A single-center quaternary-care academic institution. SUBJECTS: Children admitted to the PICU between November 2019 and April 2020. INTERVENTIONS: Providers assigned PCPC scores as part of daily workflow. Investigators assigned scores using retrospective chart review. MEASUREMENTS AND MAIN RESULTS: Of 803 patients admitted to the PICU, 782 survived and were included. Admission and discharge scores were recorded in 95% and 90% of patients, respectively. Agreement between provider- and investigator-assigned scores was excellent, with a weighted kappa of 0.87 (95% CI, 0.84-0.90) and 0.80 (95% CI, 0.76-0.84) for admission and discharge. CONCLUSIONS: Provider-assigned PCPC scores, documented as standard of care, are largely concordant with retrospective investigator-assigned scores. Measurement of cognitive functional status can be successfully integrated into daily provider workflow for use in the clinical, quality improvement, and research arenas.

Race and Ethnicity Reporting and Representation in Pediatric Clinical Trials.

BACKGROUND AND OBJECTIVES: Representative enrollment of racial and ethnic minoritized populations in biomedical research ensures the generalizability of results and equitable access to novel therapies. Previous studies on pediatric clinical trial diversity are limited to subsets of journals or disciplines. We aimed to evaluate race and ethnicity reporting and representation in all US pediatric clinical trials on ClinicalTrials.gov. METHODS: We performed a cross-sectional study of US-based clinical trials registered on ClinicalTrials.gov that enrolled participants aged <18 years old between October 2007 and March 2020. We used descriptive statistics, compound annual growth rates, and multivariable logistic regression for data analysis. Estimates of US population statistics and disease burden were calculated with the US Census, Kids' Inpatient Database, and National Survey of Children's Health. RESULTS: Among 1183 trials encompassing 405 376 participants, race and ethnicity reporting significantly increased from 27% in 2007 to 87% in 2018 (P < .001). The median proportional enrollment of Asian American children was 0.6% (interquartile range [IQR], 0%-3.7%); American Indian, 0% (IQR, 0%-0%); Black, 12% (IQR, 2.9%-28.4%); Hispanic, 7.1% (IQR, 0%-18.6%); and white 66.4% (IQR, 41.5%-81.6%). Asian American, Black, and Hispanic participants were underrepresented relative to US population demographics. Compared with expected proportions based on disease prevalence and hospitalizations, Asian American and Hispanic participants were most consistently underrepresented across diagnoses. CONCLUSIONS: While race and ethnicity reporting in pediatric clinical trials has improved, the representative enrollment of minoritized participants remains an ongoing challenge. Evidence-based and policy solutions are needed to address these disparities to advance biomedical innovation for all children.

A Cross-sectional Study Characterizing Pediatric Temperature Percentiles in Children at Well-Child Visits.

BACKGROUND: Temperature measurement plays a central role in determining pediatric patients' disease risk and management. However, current pediatric temperature thresholds may be outdated and not applicable to children. OBJECTIVE: To characterize pediatric temperature norms and variation by patient characteristics, time of measurement, and thermometer route. METHODS: In this cross-sectional study, we analyzed 134,641 well-child visits occurring between 2014-2019 at primary care clinics that routinely measured temperature. We performed bivariate and multivariable quantile regressions with clustered standard errors to determine temperature percentiles and variation by age, sex, time of measurement, and thermometer route. We performed sensitivity analyses: 1) using a cohort that excluded visits with infectious diagnoses that could explain temperature aberrations and 2) including clinic as a fixed effect. RESULTS: The median rectal temperature for visits of infants ≤12 months old was 37.2˚C, which was 0.4˚C higher than the median axillary temperature. The median axillary temperature for children 1-18 years old was 36.7˚C, which was 0.1˚C lower than the median values of all other routes. The 99th percentile for rectal temperatures in infants was 37.8˚C and the 99.9th percentile for axillary temperatures in children was 38.5˚C. Adjusted analyses did not demonstrate clinically significant variation in temperature by sex, age, or time of measurement. CONCLUSIONS: These updated temperature norms can serve as reference values in clinical practice and should be considered in the context of thermometer route used and the clinical condition being evaluated. Variations in temperature values by sex, age, and time of measurement were not clinically significant.

The association of preconception paternal metabolic syndrome on early childhood emergency department visits and hospitalizations.

BACKGROUND: Increasing preconception paternal comorbidity has been associated with adverse pregnancy outcomes. However, whether the father's health impacts the child after birth is uncertain. OBJECTIVES: In the present study, we examined the association of preconception paternal metabolic syndrome status with childhood emergency department visits and hospitalizations. MATERIALS AND METHODS: This is a longitudinal cohort study of children (295,355 boys and 278,735 girls) born to linked pairs of fathers and mothers in the United States between 2009 and 2016 within the IBM MarketScan Research database. Associations between paternal and maternal metabolic syndrome component diagnoses and subsequent hospitalizations and emergency department visits for offspring within the first 2 years of life were determined. RESULTS: Note that, 35.5% (203,617/574,090) of children had at least one emergency room visit and 6.1% (35,141/574,090) of children had an inpatient admission. After adjustment, the odds of inpatient admission and emergency department visits increased in a dose-dependent fashion among fathers with higher comorbidities. Similar trends were seen for emergency department visit utilization. DISCUSSION AND CONCLUSION: Increasing paternal preconception comorbidity is associated with a higher risk that a child requires the emergency department and inpatient care in the first years of life. An opportunity exists to engage men in preconception counseling to optimize their and their offspring's health.

Duration of Antibiotic Therapy for Bacterial Meningitis in Young Infants: A Systematic Review.

BACKGROUND AND OBJECTIVES: Recommendations for parenteral antibiotic therapy duration in bacterial meningitis in young infants are based predominantly on expert consensus. Prolonged durations are generally provided for proven and suspected meningitis and are associated with considerable costs and risks. The objective of the study was to review the literature on the duration of parenteral antibiotic therapy and outcomes of bacterial meningitis in infants <3 months old. METHODS: We searched PubMed, Embase, and the Cochrane Library for publications until May 31, 2021. Eligible studies were published in English and included infants <3 months old with bacterial meningitis for which the route and duration of antibiotic therapy and data on at least 1 outcome (relapse rates, mortality, adverse events, duration of hospitalization, or neurologic sequelae) were reported. RESULTS: Thirty-two studies were included: 1 randomized controlled trial, 25 cohort studies, and 6 case series. The randomized controlled trial found no difference in treatment failure rates between 10 and 14 days of therapy. One cohort study concluded that antibiotic courses >21 days were not associated with improved outcomes as compared with shorter courses. The remaining studies had small sample sizes and/or did not stratify outcomes by therapy duration. Meta-analysis was not possible because of the heterogeneity of the treatments and reported outcomes. CONCLUSIONS: Rigorous, prospective clinical trial data are lacking to determine the optimal parenteral antibiotic duration in bacterial meningitis in young infants. Given the associated costs and risks, there is a pressing need for high-quality comparative effectiveness research to further study this question.

Healthcare utilization in children across the care continuum during the COVID-19 pandemic.

OBJECTIVES: Healthcare utilization decreased during the COVID-19 pandemic, likely due to reduced transmission of infections and healthcare avoidance. Though various investigations have described these changing patterns in children, most have analyzed specific care settings. We compared healthcare utilization, prescriptions, and diagnosis patterns in children across the care continuum during the first year of the pandemic with preceding years. STUDY DESIGN: Using national claims data, we compared enrollees under 18 years during the pre-pandemic (January 2016 -mid-March 2020) and pandemic (mid-March 2020 through March 2021) periods. The pandemic was further divided into early (mid-March through mid-June 2020) and middle (mid-June 2020 through March 2021) periods. Utilization was compared using interrupted time series. RESULTS: The mean number of pediatric enrollees/month was 2,519,755 in the pre-pandemic and 2,428,912 in the pandemic period. Utilization decreased across all settings in the early pandemic, with the greatest decrease (76.9%, 95% confidence interval [CI] 72.6-80.5%) seen for urgent care visits. Only well visits returned to pre-pandemic rates during the mid-pandemic. Hospitalizations decreased by 43% (95% CI 37.4-48.1) during the early pandemic and were still 26.6% (17.7-34.6) lower mid-pandemic. However, hospitalizations in non-psychiatric facilities for various mental health disorders increased substantially mid-pandemic. CONCLUSION: Healthcare utilization in children dropped substantially during the first year of the pandemic, with a shift away from infectious diseases and a spike in mental health hospitalizations. These findings are important to characterize as we monitor the health of children, can be used to inform healthcare strategies during subsequent COVID-19 surges and/or future pandemics, and may help identify training gaps for pediatric trainees. Subsequent investigations should examine how changes in healthcare utilization impacted the incidence and outcomes of specific diseases.
